Description

Technical Field

[0001] The invention belongs to the technical field of emulsion explosive packaging, in particular to an emulsion explosive packaging machine. Background Art

[0002] Emulsion explosives are a new type of industrial explosives with special physical structure and special chemical properties. During production, they need to be made into long cylindrical shapes. After forming, multiple cylindrical explosive strips need to be packaged. Due to their high production efficiency and fast production speed of finished products, it is generally difficult to achieve efficient packaging by manual labor, and mechanical equipment is needed to carry out the packaging work.

[0003] A Chinese patent with the announcement number CN111532505B discloses an automatic opening device for emulsion explosive packaging, including a material strip conveyor belt, a workbench and a finished product conveyor belt, characterized in that the workbench is provided with a first workbench and a second workbench, the material strip conveyor belt is arranged above one side of the first workbench, and the finished product conveyor belt is arranged at the end of the second workbench, and also includes: a material strip arrangement mechanism, the material strip arrangement mechanism is arranged on the first workbench; a bag support mechanism, the bag support mechanism is arranged on the second workbench, the bag support mechanism includes a driving component, a track member and an opening component; and a bag taking mechanism, the bag taking mechanism includes a bracket and a bag taking component. By utilizing a rotatable bag support mechanism, the opening action of the support plate is completed while it rotates, ensuring that the contact surface of the bag support mechanism is small when the feeding bag is just rotated, and the bag is fully opened when it is rotated into place, solving the problem that the opening mechanism cannot accurately enter the bag, causing the bag to be stuck and affecting work efficiency.

[0004] In the above technology, the emulsion explosive is squeezed into the packaging bag to form a medicine roll. Since the emulsion explosive may be mixed with metal debris during the production process, this metal impurity is mixed with the emulsion explosive. When it is hit or rubbed during packaging or transportation, it may cause an explosion, posing a safety hazard; and the two ends of the medicine roll are locked by buckles. Some buckles are not firmly sealed due to edge knocking, or even fall off, resulting in poor sealing of the medicine roll, which is easy to flow out when squeezed during transportation, which not only easily pollutes the environment, but also fails to achieve the power of the explosives.

DETAILED DESCRIPTION

[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0040] like Figures 1 to 10 As shown, an emulsion explosive packaging machine according to an embodiment of the present invention comprises: a first conveyor 1; a silo 12, a detection unit fixed at one end of the top of the first conveyor 1 by four pillars 11, and used to detect defects of emulsion explosive rolls; the detection unit comprises a detection plate 21 and a scanner 31; the top two ends of the first conveyor 1 are symmetrically fixed with fixed plates 2; the bottom two ends of the detection plate 21 are respectively fixed to the fixed plate 2; an inductor coil is installed at the bottom of the detection plate 21; a first controller 23 is fixed to the outer side wall of one of the fixed plates 2; a first mounting frame 22 is fixed to the side walls of the two fixed plates 2 away from the silo 12; the first mounting frame 22 is rotatably connected to a first reciprocating screw rod 24 through a bearing; the first mounting frame 2 2 is fixedly connected to the side wall of the conveyor 1; the output shaft of the first motor 28 is fixedly connected to one end of the first reciprocating screw 24; the first reciprocating screw 24 is threadedly connected to the first movable plate 27; the bottom of the first movable plate 27 is fixedly connected to the first push plate 26; the first movable plate 27 is slidably connected to two first guide rods 25; both ends of the first guide rods 25 are fixedly connected to the first mounting frame 22; the first controller 23 is electrically connected to the first motor 28; the top of the first conveyor 1 is fixedly connected to the first fixed frame 3; the first fixed frame 3 is arranged on the side of the detection plate 21 away from the silo 12; two scanners 31 are symmetrically fixedly connected to the bottom of the first fixed frame 3; the second controller 33 is fixedly connected to the outer side wall of the first fixed frame 3.

[0041] Emulsion explosives are squeezed into packaging bags to form medicine rolls. Since emulsion explosives may be mixed with metal debris during the production process, such metal impurities are mixed with emulsion explosives. When they are hit or rubbed during packaging or transportation, they may cause explosions, posing safety hazards. In addition, the two ends of the medicine roll are locked by buckles. Some buckles are not firmly sealed due to edge knocking, or even fall off, resulting in poor sealing of the medicine roll. It is easy to flow out when squeezed during transportation, which not only easily pollutes the environment, but also fails to achieve the power of the explosives.

[0042] When the detection unit provided by the present invention is in use, the medicine roll is unloaded from the silo 12 to the first conveyor 1, and the medicine roll is conveyed by the first conveyor 1. When passing through the detection plate 21, after signal analysis, if there is metal debris, when the metal particles pass through the inductor coil passing alternating current, eddy currents are formed inside the metal debris, the metal debris particles are magnetized, the magnetized debris will generate a new magnetic field, and the magnetic induction intensity inside the debris is much greater than the magnetic induction intensity generated by the internal eddy current, so when the metal debris passes through the inductor coil, the equivalent inductance value of the inductor coil increases, and the first controller 23 controls the first motor 28 to start, and the first reciprocating screw 24 rotates through the first motor 28, and the first reciprocating screw 24 drives the first movable plate 27 to move, and the first movable plate 27 drives the first push plate 26 to move horizontally on the first guide rod 25, so that the medicine roll is quickly pushed out, and the movable plate is quickly reset; the medicine roll without metal debris continues to be conveyed;

[0043] When the medicine roll continues to be conveyed through the scanner 31, when the scanner 31 detects that there is a problem with the buckle, the medicine roll is pushed out through the second controller 33, and the medicine roll with qualified buckle will continue to be conveyed.

[0044] like Figure 1 and Figure 4 As shown, a second mounting frame 32 is fixedly connected to the side wall of the first fixed frame 3 away from the detection plate 21; a second reciprocating screw rod 34 is rotatably connected to the inside of the second mounting frame 32 through a bearing; a second motor 38 is fixedly connected to the side wall of the second mounting frame 32; an output shaft of the second motor 38 is fixedly connected to one end of the second reciprocating screw rod 34; a second movable plate 37 is threadedly connected to the second reciprocating screw rod 34; a second push plate 36 is fixedly connected to the bottom of the first movable plate 27; two second guide rods 35 are slidably connected to the second movable plate 37; both ends of the first guide rod 25 are fixedly connected to the second mounting frame 32; the second controller 33 is electrically connected to the second motor 38.

[0045] When the second push plate 36 provided by the present invention is in use, when the scanner 31 detects a problem with the buckle, a signal is transmitted to the second controller 33, and the second motor 38 is turned on by the second controller 33. The second motor 38 drives the second reciprocating screw 34 to rotate, and the second reciprocating screw 34 drives the second movable plate 37 to move. The second movable plate 37 slides on the second guide rod 35, and the second movable plate 37 is limited in the horizontal direction by the second guide rod 35. The second movable plate 37 drives the second push plate 36 to move, and the second push plate 36 pushes the medicine roll out, and then the second push plate 36 is reset.

[0046] like Figure 1 and Figure 5As shown, two defective product boxes 5 are provided on one side of the first conveyor 1; the defective product boxes 5 on both sides are aligned with the first push plate 26 and the second push plate 36 respectively; the top of the defective product box 5 is rotatably connected to a buffer plate 51 through a rotating shaft; the bottom of the buffer plate 51 is fixedly connected to two springs 52, and the bottom of the spring 52 is fixedly connected to the side wall of the defective product box 5.

[0047] When the buffer plate 51 provided by the present invention is in use, when unqualified medicine rolls are pushed to the defective box 5, they pass through the buffer plate 51. Under the action of the spring 52, the buffer plate 51 has the function of buffering and reciprocatingly shaking around the rotating shaft, so that the medicine rolls can slowly slide down to the defective box 5 with the help of the buffer plate 51, preventing the medicine rolls containing metal debris from colliding, and at the same time reducing the overflow of unqualified products from the defective box 5.

[0048] like Figure 1 and Figure 6 As shown, a workbench 6 is provided on the side of the first conveyor belt away from the silo 12; two limit plates 63 are fixedly connected to the workbench 6, and the limit plates 63 are aligned with the discharge end of the first conveyor 1; a second electric push rod 61 is fixedly connected to the top of the workbench 6; a top plate 62 is fixedly connected to the output end of the second electric push rod 61; and the top plate 62 is arranged between the two limit plates 63.

[0049] When the limiting plate 63 provided by the present invention is in use, the medicine rolls are output from the output end of the first conveyor 1 to the workbench 6. The medicine rolls are neatly arranged by the limiting plate 63, which facilitates the packaging of multiple medicine rolls together.

[0050] like Figure 1 and Figure 6 As shown, a notch is formed at the top of the limit plate 63 close to the first conveyor 1 , and a slanted plate 64 is fixedly connected thereto; a photoelectric control mechanism 65 is fixedly connected to the top of the slanted plate 64 ; and the photoelectric control mechanism 65 is electrically connected to the second electric push rod 61 .

[0051] When the photoelectric control mechanism 65 provided by the present invention is in use, the qualified medicine rolls on the first conveyor 1 slide down through the inclined plate 64, and will slide from the photoelectric control mechanism 65 after passing through the inclined plate 64. The photoelectric control mechanism 65 counts, and when the set number is reached, it means that the number of medicine rolls has been reached, and the second electric push rod 61 can be driven to push.

[0052] like Figure 6 and Figure 7As shown, a placement groove is provided on the top of the workbench 6; a rotating plate 66 is rotatably connected in the placement groove through a rotating shaft; a groove 661 is provided on the top of the workbench 6; the rotating shaft extends to the groove 661 and a gear 664 is fixedly connected therein; a third electric push rod 662 is fixedly connected in the groove 661; a rack 663 is fixedly connected to the output end of the electric push rod; the rack 663 is meshed with the gear 664; a limit block 665 is fixedly connected to the bottom of the rack 663; the limit block 665 slides at the bottom of the groove 661.

[0053] When the gear 664 and the rack 663 provided by the present invention are in use, the medicine roll slides onto the rotating plate 66 through the inclined plate 64, and the third electric push rod 662 is electrically connected to the photoelectric control mechanism 65. When the number of medicine rolls reaches the set value, the third electric push rod 662 is controlled to be opened, and the rack 663 is driven to move by the third electric push rod 662. The rack 663 moves in the horizontal direction through the limit block 665, and the rack 663 drives the gear 664 to rotate. The gear 664 drives the rotating plate 66 to rotate through the rotating shaft. The rotating plate 66 rotates to be flush with the workbench 6, so that the top medicine roll can be pushed through the top plate 62, and then the rotating plate 66 is rotated again to the bottom of the inclined plate 64.

[0054] like Figure 1 and Figure 8 As shown, a side plate 7 is provided on the side of the workbench 6 away from the second electric push rod 61; a disc 71 is rotatably connected to the side plate 7 through a bearing; four through holes 73 are arranged circumferentially in the disc 71; four bag-supporting frames 72 are fixedly connected to the side wall of the through hole 73 away from the workbench 6; the through holes 73 are respectively matched with the top plate 62 and the bag-supporting joint; a mounting seat 74 is fixedly connected to the side wall of the side plate 7 close to the workbench 6; a telescopic air gun 75 is fixedly connected to the top of the mounting seat 74, and the air outlet end of the telescopic air gun 75 is inserted in the through hole 73; a third motor 76 is fixedly connected to the mounting seat 74; the output shaft of the third motor 76 is fixedly connected to the disc 71 through the mounting seat 74; a second conveyor 9 is provided below the bag-supporting frame 72.

[0055] When the bag-supporting frame 72 and the disc 71 provided by the present invention are used, the packaging bag is sleeved on the bag-supporting frame 72 above, and then the telescopic air gun 75 is driven to inflate the packaging bag so that the packaging bag swells. The third motor 76 is driven to rotate through the output shaft of the third motor 76. When the disc 71 rotates to be flush with the workbench 6, the second electric push rod 61 drives the top plate 62 to push the medicine roll out of the limit plate 63 and into the packaging bag on the bag-supporting frame 72 through the opening 73. At the same time, the packaging bag is pushed and falls on the second conveyor 9. During the rotation of the disc 71, the packaging bag can be sleeved on the bag-supporting frame 72 and the medicine roll can be pushed into the packaging bag at the same time. The operation is orderly and the packaging efficiency is improved. The packaging bag on the second conveyor 9 is heat-sealed to complete the packaging.

[0056] like Figure 1 and Fig. 9 As shown, a bag storage box 8 is provided on the side of the second conveyor 9 away from the side plate 7; two cross bars 81 are symmetrically fixed to the top of the bag storage box 8; upper and lower layers of bag conveying rollers 82 are provided in the cross bars 81; the tops and bottoms of the two cross bars 81 are respectively fixed to fixed seats 83; the middle parts of the fixed seats 83 are fixed to fourth electric push rods 84; the output ends of the fourth electric push rods 84 are fixed to movable boxes 85; cylinders 851 are symmetrically fixed to the two movable boxes 85; the output ends of the cylinders 851 extend to the movable box 85 and are fixed to a lifting plate 853; two suction nozzles 852 are fixed to the lifting plate 853; the suction nozzles 852 are slidably connected to the movable box 85.

[0057] When the bag conveying roller 82 and the suction nozzle 852 provided by the present invention are in use, the packaging bag is output from the bag storage box 8 and transported by the bag conveying roller 82. When the bag needs to be put on, the cylinder 851 is turned on, and the cylinder 851 drives the suction nozzle 852 to move toward the packaging bag through the lifting plate 853 to suck the packaging bag. At this time, the fourth electric push rod 84 is turned on, and the fourth electric push rod 84 drives the movable box 85, the suction nozzle 852 and the packaging bag forward, and separates them to both sides through the cylinder 851, so that the packaging bag opens, and the fourth electric push rod 84 puts the opened packaging bag on the bag supporting frame 72 to achieve the effect of bagging and supporting the bag.

[0058] like Figure 1 and Figure 2 As shown, a feeding roller 13 is rotatably connected to the material bin 12 via a rotating shaft; a plurality of arc grooves 14 are arranged circumferentially on the outer side of the feeding roller 13; and a driving motor is provided on one side of the feeding roller 13.

[0059] When the unloading roller 13 provided by the present invention is in use, the driving motor is turned on, the driving motor drives the unloading roller 13 to rotate, and the unloading roller 13 drives the arc groove 14 to rotate. The medicine rolls in the silo 12 fall into the arc groove 14, rotate with the arc groove 14 to the bottom of the unloading roller 13, and finally fall on the first conveyor 1, thereby realizing orderly loading of medicine rolls and facilitating detection.

[0060] like Figure 1 As shown, a second fixing frame 4 is fixedly connected to one end of the top of the first conveyor 1 away from the silo 12 ; a first electric push rod 41 is fixedly connected to the top of the fixing frame; and a baffle 42 is fixedly connected to the output end of the first electric push rod 41 .

[0061] When the baffle 42 provided by the present invention is in use, the first electric push rod 41 is electrically connected to the photoelectric control mechanism 65. When the number of medicine rolls reaches a set value, the first electric push rod 41 is turned on, and the first electric push rod 41 moves the baffle 42 downward to block the transportation of the medicine rolls and prevent the medicine rolls from piling up on the workbench 6.

[0062] Working principle: By turning on the driving motor, the driving motor drives the unloading roller 13 to rotate, and the unloading roller 13 drives the arc groove 14 to rotate, and the medicine rolls in the silo 12 fall into the arc groove 14, rotate with the arc groove 14 to the bottom of the unloading roller 13, and finally fall on the first conveyor 1, so as to realize the orderly loading of medicine rolls;

[0063] The medicine roll is unloaded from the silo 12 onto the first conveyor 1, and is conveyed by the first conveyor 1. When passing through the detection plate 21, after signal analysis, if there is metal debris, when the metal particles pass through the inductor coil passing alternating current, eddy currents are formed inside the metal debris, the metal debris particles are magnetized, the magnetized debris will generate a new magnetic field, and the magnetic induction intensity inside the debris is much greater than the magnetic induction intensity generated by the internal eddy currents, so when the metal debris passes through the inductor coil, the equivalent inductance value of the inductor coil increases, and the first controller 23 controls the start of the first motor 28, and the first reciprocating screw 24 rotates through the first motor 28, and the first reciprocating screw 24 drives the first movable plate 27 to move, and the first movable plate 27 drives the first push plate 26 to move horizontally on the first guide rod 25, so that the medicine roll is quickly pushed out, and the movable plate is quickly reset; the medicine roll without metal debris continues to be conveyed;

[0064] When the medicine roll continues to be transported through the scanner 31, when the scanner 31 detects that there is a problem with the buckle, the medicine roll is pushed out through the second controller 33, and the second motor 38 is turned on. The second motor 38 drives the second reciprocating screw 34 to rotate, and the second reciprocating screw 34 drives the second movable plate 37 to move. The second movable plate 37 slides on the second guide rod 35, and the second movable plate 37 is limited in the horizontal direction by the second guide rod 35. The second movable plate 37 drives the second push plate 36 to move, and the second push plate 36 pushes the medicine roll out. Subsequently, the second push plate 36 is reset, and the medicine roll with qualified buckle continues to be transported;

[0065] The qualified medicine rolls on the first conveyor 1 slide down through the inclined plate 64, and will slide from the photoelectric control mechanism 65 after passing through the inclined plate 64. The photoelectric control mechanism 65 counts, and when the set number is reached, it means that the number of medicine rolls has been reached, and the medicine rolls slide down through the inclined plate 64 onto the rotating plate 66. The third electric push rod 662 is electrically connected to the photoelectric control mechanism 65. When the number of medicine rolls reaches the set value, the third electric push rod 662 is controlled to be opened, and the rack 663 is driven to move by the third electric push rod 662. The rack 663 moves in the horizontal direction through the limit block 665, and the rack 663 drives the gear 664 to rotate. The gear 664 drives the rotating plate 66 to rotate through the rotating shaft. The rotating plate 66 rotates and is flush with the workbench 6, so that the top medicine roll can be pushed through the top plate 62, and then the rotating plate 66 is rotated again to the bottom of the inclined plate 64;

[0066] The packaging bag is output from the bag storage box 8 and conveyed by the bag conveying roller 82. When the bag needs to be put on, the cylinder 851 is turned on. The cylinder 851 drives the suction nozzle 852 to move toward the packaging bag through the lifting plate 853 to suck the packaging bag. At this time, the fourth electric push rod 84 is turned on. The fourth electric push rod 84 drives the movable box 85, the suction nozzle 852 and the packaging bag forward and separates them to both sides through the cylinder 851, so that the packaging bag opens. The fourth electric push rod 84 sets the opened packaging bag on the bag supporting frame 72 to achieve the effect of bagging and supporting the bag.

[0067] The packaging bag is placed on the bag support frame 72 above, and then the telescopic air gun 75 is driven to inflate the packaging bag so that the packaging bag swells. The third motor 76 is driven to rotate the disc 71 through the output shaft of the third motor 76. When the disc 71 rotates flush with the workbench 6, the second electric push rod 61 drives the top plate 62 to push the medicine roll out of the limit plate 63 and into the packaging bag on the bag support frame 72 through the opening 73. At the same time, the packaging bag is pushed and falls on the second conveyor 9. During the rotation of the disc 71, the packaging bag can be placed on the bag support frame 72 and the medicine roll can be pushed into the packaging bag at the same time. The operation is orderly and the packaging efficiency is improved. The packaging bag on the second conveyor 9 is heat-sealed to complete the packaging.
